moon-web System Requirements Document

Introduction

The "moon-web" project is focused on developing a visually engaging vehicle auction web application. This document outlines the system requirements for creating a web app that provides a seamless user experience for vehicle auctions, with a specific focus on a polished UI design.

System Overview

The moon-web application is designed to facilitate vehicle auctions with a modern and clean user interface. The application will feature a blurred background of a vehicle auction page with a centered modal dialog that displays auction completion details and similar live auctions. The app aims to provide a responsive and interactive experience for users, ensuring accessibility across various devices.

Functional Requirements

• As a User, I should be able to view a blurred vehicle auction page in the background.
• As a User, I should see a modal dialog with a close X button in the top right corner.
• As a User, I should see a circular blue success/check icon at the top of the modal.
• As a User, I should see an "Auction Completed" pill badge in the modal.
• As a User, I should see the heading "This Auction Has Ended" in the modal.
• As a User, I should read explanatory text about the live bidding session being completed.
• As a User, I should click a blue "Back to mainscreen" button in the modal.
• As a User, I should see "Similar Live Auctions" with subtitle text below a divider in the modal.
• As a User, I should see a large auction card with a motorcycle hero image.
• As a User, I should see a "Timed Auction" badge on the auction card.
• As a User, I should see the title "Ultimate Ride Auction: Cars & Motorcycles Galore!" on the auction card.
• As a User, I should see bid text "Bid starts from RM 58,000" on the auction card.
• As a User, I should see time left "2h 45m" on the auction card.
• As a User, I should click a full-width blue "View auction" button on the auction card.

User Personas

• Individual Buyer: Interested in purchasing vehicles through auctions.
• Dealership: Looking to acquire vehicles for resale.
• Guest User: Browsing auctions without registration.

Visuals Colors and Theme

• primary: #1E3A8A (deep blue)
• primary_light: #3B82F6 (light blue)
• secondary: #F97316 (orange)
• accent: #10B981 (emerald green)
• highlight: #F59E0B (amber)
• bg: #F3F4F6 (light gray)
• surface: rgba(255, 255, 255, 0.9) (white with transparency)

• text_muted: #6B7280 (muted gray)
• border: rgba(209, 213, 219, 0.5) (light gray)

Signature Design Concept

The moon-web application will feature an interactive homepage with a "Living Auction Gallery" concept. The homepage will display a dynamic 3D carousel of auction items, using @react-three/fiber for rendering. Users can click and drag to rotate the carousel, revealing different auction items in a 3D space. Each item will animate into focus with a spring effect using framer-motion, providing details and a call-to-action button. The background will subtly change colors based on the time of day, creating an immersive experience.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, providing layered depth via scroll. Decorative elements will translate at different speeds, while main content scrolls naturally. This model will enhance storytelling and create a visually rich first impression. Internal pages, such as dashboards and settings, will adopt a "static" model for clarity and readability.

Non-Functional Requirements

• The application must be responsive and accessible on devices with a minimum width of 360px.
• The UI should maintain performance standards with smooth animations and transitions.
• The application should support multiple languages and locales, with a focus on English and Hindi.

Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• AI Models: GPT 5.4 for user-friendly responses
• Local Orchestration: Docker, docker-compose

Assumptions and Constraints

• The application will primarily target users in India, with currency displayed in INR.
• User registration and authentication will be required for bidding.
• The application will be hosted on a cloud platform supporting Docker containers.

Glossary

• Modal: A dialog box/popup window that is displayed on top of the current page.
• Parallax: A scrolling technique where background images move slower than foreground images, creating an illusion of depth.
• Responsive Design: An approach to web design that makes web pages render well on a variety of devices and window or screen sizes.
• 3D Carousel: A rotating display of items in a three-dimensional space, allowing users to interact with the items by rotating the view.
